It computes MD5 checksums of fragments of the body of an e-mail and
compares them to those of know spam. As such it works similar to the
now standard plugins that use the Pyzor, Razor and DCC software
packages from within SpamAssassin.

The code can be downloaded via the links at this project's summary
page @ sourceforge.net.

CREDITS

The iXhash plugin is based on parts of the 'NiX Spam' project by Bert Ungerer of
Heise Verlag, Germany. The (German) pages of that project can be reached at http://www.nixspam.org or http://www.heise.de/ix/nixspam/.
The procmail code producing the hashes only can be found at ftp://ftp.ix.de/pub/ix/ix_listings/2004/05/checksums.

NB: Although this project is on friendly terms with Heise Verlag, it should be noted that this project has no connection to Heise itself apart from using the same algorithm to compute hashes and the resulting
interoperatibility.

Big thanks go out to the folks @ Hosteurope who
support this project by donating a dedicated server use to provide the
list data!
